Front

What is the total current through a circuit if it measures 0.02 amps?

Back

The total current through the circuit is 0.02 amps.

Front

What happens to the total resistance when resistors are added in series?

Back

The total resistance increases.

Front

What occurs if one light bulb is removed from a parallel circuit?

Back

The other bulbs will stay on.

Front

What is the relationship between resistance and current in a circuit?

Back

As the resistance of a circuit increases, the current will decrease.

Front

What is the total resistance in a circuit if it measures 450 ohms?

Back

The total resistance in the circuit is 450 ohms.

Front

Define 'current' in the context of electrical circuits.

Back

Current is the flow of electric charge, measured in amps.

Front

What is 'resistance' in an electrical circuit?

Back

Resistance is the opposition to the flow of current, measured in ohms.

Front

What is the formula for calculating total resistance in series circuits?

Back

Total resistance (R_total) = R1 + R2 + R3 + ... + Rn.

Front

What is the formula for calculating total current in a circuit?

Back

Total current (I) = Voltage (V) / Total Resistance (R).

Front

What happens to the total current if the voltage in a circuit is increased while resistance remains constant?

Back

The total current will increase.
