Answer: 126 volts
Step-by-step 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.
