Electricity Review

The electric potential difference between two points.

• Current

• Electron

• Voltage

• Resistance

The opposition to the flow of charge.

• Voltage

• Current

• Electrons

• Resistance

According to Ohm's Law, what would you need to do to the resistance of a circuit if you doubled the voltage and wanted the current to remain the same?

• half the resistance

• double the resistance

• divide the resistance by 3

• triple the resistance

The circuit type in which the loads all have the same current is....

• parallel

• series

• alternating

• direct

A ________________ is purposefully added to a circuit in order to limit the current to protect other parts of the circuit.

• wire

• battery

• resistor

• switch

When we talk about current, we talk about it flowing from the positive end to the negative end of the battery. This is known as _______________ current.

• conventional

• electron

• alternating

• direct

Why is it a bad idea to create this circuit?

In other words: what is missing from this circuit and why do we say that particular thing is required for a circuit?

• a very large current will flow

• there will be a large voltage difference

• no current will flow

• charge will build up in the wire

What type of circuit is this?

• Alternating circuit

• Parallel circuit

• Series circuit

• Conventional circuit

When calculating equivalent resistance for a parallel circuit, the equivalent resistance is always __________________ any of the individual resistors.

• less than

• more than

• equal to

• unrelated to

An Ampere is equivalent to...

• J/s

• Cs

• I/s

• C/s
