# Find The Voltage V2 Across Wire 2.

by -3 views

Wire 3 has resistance and cross-sectional area. The supply voltage is shared between components in a series circuit so the sum of the voltages across all of the components in a series circuit is equal to the supply voltage V_s.

### Wire 1 has resistance and cross-sectional area Wire 2 has resistanc.

Find the voltage v2 across wire 2.. Remember that current I is the battery voltage 9 V divided by the total resistance R1 R2 or approximately. The resistance of the wire ohmsmeter is rather low so there is very little votage drop between 2 points on the wire. If the resistance of the wire between the two prongs is very small say 11000 ohms and a current of 1 Amp is flowing there will be a voltage drop of 11000.

Wire 4 has resistance and cross-sectional area. Each parallel wire has the same voltage as the entire circuit. Single-phase voltages are usually 115V or 120V while three-phase voltages are typically 208V 230V or 480V.

Amperes – Enter the maximum current in amps that will flow through the circuit. Written by Willy McAllister. You know the value of each resistor and you know the current flowing through each resistor.

A voltage V0 is applied across the series as shown in the figureFind the voltage V2 across wire 2Give your answer in terms of V0 the voltage of the battery. Four wires are madeof the same highly resistive material cut to the same length andconnected in series. V1 12A x 5 Ohms 6 V.

Here the voltage 7V can be seen dropped to 3V. Wire 1 has resistance. Get the detailed answer.

A voltage V0 is applied across the series as shown in the figure. Wire 2 has resistance and cross-sectional area. Next we calculate the amperage in the circuit.

If you know the voltage across the whole circuit the answer is surprisingly easy. Now if we consider points D and E we find the voltage drop is 4V. How to calculate voltage.

The Node Voltage Method solves circuits with the minimum number of KCL equations. The voltage across the left resistor is 6 volts and the voltage across the right resistor is 6 volts. Voltage – Enter the voltage at the source of the circuit.

Actually there is a voltage drop between any two points along the wire – but it will be small because the resistance of the wire is small even the wire has a few pebbles in it. The confusion enters when I try to calculate the voltage drop with this 6awg wire plus the potentially 8awg wire that runs 15 feet from the battery to the circuit breaker. Through online sources I was able to determine that at the 45amp max 6awg wire could handle it with a 5 voltage drop.

Wire 4 has resistance R4 and cross-sectional area 4A. Lets say a circuit with two parallel resistors is powered by a 6 volt battery. Find the voltage V2 across wire 2.

Ultimately across the points F and G the voltage drop appears to be 3V. To figure out how much voltage is dropped across each resistor you use Ohms Law for each individual resistor. Wire 2 has resistance R2 and cross-sectional area 2A.

A voltage is applied across the series as shown in the figure. I V RT 12V 10 Ohms 12 Amp. Wire 3 has resistance R3 and cross-sectional area 3A.

If youre seeing this message it means were having trouble loading external resources on our website. In the first loop V1 is the voltage source which is supplying 28V across R1 and R2 and in the second loop. The following example will go through the process of how you can calculate the voltage between two.

If the wire was very long or very small the resistance would be greater and then there could be a measurable voltage drop between the 2 points. Written by Willy McAllister. Give your answer in terms of V0 the voltage of the battery.

Wire 1 has resistance and cross-sectional area. This point has the same voltage as this point because there are no resistors in between. And when there is no resistance the potential difference is always zero within a wire across any two points in a wire so the voltage is the same.

This is connected to two opposite points along a device and the voltage drop across the device is known as the difference. For motors it is recommended to multiply the nameplate FLA by 125 for wire sizing. A wire would always have the same voltage anywhere.

Here are two different voltage sources providing different voltages across two loop paths. Meaning the original source voltage 9V here turns into 7V. At this stage the voltage 3V turns into 0V.

Wire 4 has resistance R4 and cross-sectional area 4A. V2 is the voltage source providing 7V across R3 and R2. The Node Voltage Method solves circuits with the minimum number of KCL equations.

Wire 3 has resistance R3 and cross-sectional area 3A. The resistor R2 is common in both cases. Now that we know the amperage for the circuit remember the amperage does not change in a series circuit we can calculate what the voltage drops across each resistor is using Ohms Law V I x R.

When using one of these reference points as ground it provides the total voltage at that point.

Were assuming the wires dont have any resistances.
