What is the Voltage of a circuit that has a resistance of 5 Ω and a current of 2 A?

25 V

10 V

2.5 V

0.4 V

If the battery produced 12.6 Volts what would be the current flow for a 6 Ohm resistor?

2.1 Amps

2.4 Amps

1.71 Amps

15 Amps

How many Volts would we need to produce a current flow of 8 Amps through a 6 Ohm resistor

12 volts

24 volts

1.3333

48 volts

This circuit has a 24 volt battery and the resistor is 8 ohms. How many amps are running through the circuit?

3 Amps

192 Amps

2 Amps

4 Amps

10.

What word means how hard it is for electrons to flow through.

Current

Voltage

Resistance

Power

11.

The flow of electricity requires a

complete path

incomplete path

insulated current

complex circuit

12.

Which best describes a parallel circuit?

Electricity flows along one pathway.

The flow of electricity comes from one source.

Electricity flows along more than one pathway.

The flow of electricity comes from more than one source.

13.

What is the formula for current?

I = V / R

I = R / V

I = V x R

I = (V x R) / 2

14.

What is the formula for voltage?

V = (I x R) / 2

V = I / R

V = R / I

V = I x R

15.

What is the formula for resistance?

R = I / V

R = V / I

R = V x I

R = (V x I) / 2

16.

18Ω

36Ω

200Ω

400Ω

17.
