Unit 5 Test Review

Front

What is the effect of resistance on the current flow in a circuit?

Back

Higher resistance decreases current flow.

Front

What is the formula to calculate power in a circuit?

Back

P = IV (Power = Current x Voltage)

Front

If a circuit has 150 watts and operates on 110 volts, what is its amperage?

Back

1.36

Front

What type of circuit has components connected end-to-end?

Back

Series circuit.

Front

What type of circuit has components connected across common points?

Back

Parallel circuit.

Front

What is the effect of an open circuit?

Back

An open circuit does not allow current to flow.

Front

What is the effect of a closed circuit?

Back

A closed circuit allows current to flow.

Front

If a circuit has 8 amps and operates on 12 volts, what is its power?

Back

96

Front

What happens to current in a series circuit if one component fails?

Back

The current stops flowing.

Front

What happens to total resistance in a series circuit?

Back

Total resistance is the sum of individual resistances.
