### 5 Matching Questions

1. If the distance between the objects increases
2. If the switch is ___________, the circuit can no longer flow.
3. Ohms Law - currents are directly proportional to the potential difference and inversely proportional to the resistance.
4. What is an electric field?
5. The RATE at which chemical work is done?
1. a open
2. b the space around a charged particle
3. c then the electric force between the objects will decrease (INVERSE relationship)
4. d Potential difference (V) = current (A) x resistance ( Ω)
V = I R
5. e Power (W) = current (A) x voltage (V)
P = IV
you must label:
the watts with a P
the amps with an I
and the volts with a V

### 5 Multiple Choice Questions

1. by transferring electrons
2. the electric force between the objects will be greater - that is DIRECT relationship
3. the force (how strong) of attraction or repulsion between objects due to charge
4. series
5. the ability to move an electric charge from one point to another

### 5 True/False Questions

1. What is "charging by friction"?when an object with a charge touches an object with no charge, some electrons move from the charged to the uncharged object. The uncharged object gains electrons.

2. What is resistance?the OPPOSITION to the flow of current

3. What is a battery?A device that is a source of electric current b/c of a pd (voltage) between terminals.

4. What is a conductor?a material in which electrical charges can move freely and can carry an electric current

5. In which type of circuit is there only ONE path for the current to follow?
In a parallel circuit.
