Front

The total resistance in a series circuit is equal to:

Back

(b) sum of the resistors

Front

In a series circuit that contains five resistors, the current in each resistor is:

Back

(a) the same

Front

If eight 100 watt light bulbs are connected in parallel, and one bulb burns out, what would happen to the other seven?

Back

(b) stay the same

Front

What would be the line current on a circuit containing three light bulbs, each with a resistance of 200 ohms, connected in parallel to a supply of 110 volts?

Back

(a) 17.93 amps

Front

What would be the current flow, if the above circuit were connected in series?

Back

(a) 0.183 amps

Front

A 20 ohm, 400 ohm, and 180 ohm resistor are connected in parallel. What would be the effective resistance of the circuit?

Back

(a) 10.3 ohms

Front

The total resistance of 10 - 1200 ohm resistors connected in parallel is:

Back

(a) 10 ohms

Front

Adding resistance to a parallel circuit will cause the total resistance to increase.

Back

TRUE

Front

If ten lamps are connected in parallel, and one burns out, the remaining lamps will burn brighter.

Back

TRUE

Front

Power in a parallel circuit will be equal to the product of the total current and the total resistance.

Back

FALSE
