1
Electricity Review Jeopardy

2
These charges repel.

3
What are LIKE charges.

4
Attracts both positive and negative objects.

5
What is Neutral-charged object.

6
The symbol for current, and what it’s measured in.

7
What is “I” and “amps”.

8
This device is placed parallel to the circuit to take this measurement.

9
What is Voltmeter and “volts” or “potential difference”.

10
Measured in Watts.

11
What is Power.

12
Q and Coulombs.

13
What is the symbol for Charge and what it’s measured in.

14
Draw a circuit diagram containing a battery, a switch, two light bulbs in parallel, another light bulb in series, and an ammeter that is measuring the overall current.

16
Which has brighter light bulbs: 2 bulbs in series or 2 bulbs in parallel?

17
Two bulbs in parallel.

18
Slows the current in a circuit.

19
What are resistors.

20
Referred to as a load.

21
What is something that needs/uses energy.

22
Provide two equations that could be used to calculate Energy.

23
E = Pt or E = VQ

24
The object that becomes negatively charged after rubbing an ebonite rod with fur.

25
The ebonite rod.

26
The formula for calculating total resistance in a parallel circuit.

27
1 = 1 + 1 + 1 R T R 1 R 2 R 3

28
Solve for time, potential difference, and power if you know the following variables: R = 17 Ω Q = 25 C I = 170 A

29
t = Q = 25 = 0.147 s I 170 V = RI = (17)(170) = 2890 V P = VI = (2890)(170) = 491300 W or 49 kW

30
Copy and Solve for all Variables:

31
V 2 = 32 V V 5 = 8 V R 1 = 5.33 Ω R 4 = 0.47 Ω I o = 25 A I 1 = 6 A I 5 = 8 A
