FE(4)Electricity Principles Quiz

What is the formula for calculating total voltage in a series circuit?

• V = V1 - V2 - V3

• V = V1 * V2 * V3

• V = V1 + V2 + V3

• V = V1 / V2 / V3

In a series circuit, if the total voltage is 15V and there are three resistors, what is the average voltage drop across each resistor?

• 3V

• 5V

• 7V

• 9V

Which formula represents the current through resistor R2?

• I2 = V * R2

• I2 = V / R2

• I2 = R2 / V

• I2 = V + R2

In a parallel circuit, how does the voltage across each branch compare to the total voltage supplied to the circuit?

• It is half of the total voltage

• It is double the total voltage

• It is the same as the total voltage

• It is zero

If the current through a branch is 2 amps and the resistance is 5 ohms, what is the voltage across that branch?

• 5 volts

• 10 volts

• 15 volts

• 20 volts
