You have a series circuit of 6 amps and three resistors on it, with resistance of 10 ohms, 5 ohms, and 6 ohms, respectively. What is the voltage of this circuit?

Answer: 126 volts

Explanation:

Current of the circuit = 6 amps

Three resistors in series

R1 = 10 ohms

R2 = 5 ohms

R3 = 6 ohms

voltage of this circuit = ?

First, obtain the total resistance of the series circuit

Rtotal = R1 + R2 + R3

Rtotal = 10 ohms + 5 ohms + 6 ohms

Rtotal = 21 ohms

Now, apply the formula

Voltage = current x total resistance

Voltage = 6 amps x 21 ohms

Voltage = 126 volts

Thus, there are 126 volts of voltage in the circuit.
