1. Please bring your book tomorrow.
Bell Work: Electricity
( Voltage / Current / Resistance ) slows down the current.
( Voltage / Current / Resistance ) is supplied by the battery.
Conventional current flows ( clockwise / counter clockwise ) in a circuit diagram.
Draw the symbols for a battery and wire.
Draw the symbols for a resistor and a light bulb.
Please bring your book tomorrow.

2. Ohm’s Law
Relates potential difference and resistance to the current in a circuit.
V = I R
V: potential difference: unit volts (V)
I: current: unit amp (A)
R: resistance: unit ohm ()

3. Ohm’s Law Current is affected by changes in V and R.
V and I are directly related.
R and I are inversely related.
V and R do not affect one another.

4. Power P: power: unit Watts (W) E: energy: unit Joules (J)
The rate at which energy is used by a circuit.
P: power: unit Watts (W)
E: energy: unit Joules (J)
t: time: unit second (s)

5. Power
Power directly affected by E, I, and V.
