2.2 - V=IR Equation & I-V Graphs

Question 1

The formula which relates voltage, current, and resistance is:

Answer 1

voltage = current x resistance
V=IR

Question 2

1 FACTOR IMPACTING RESISTANCE

Answer 2

TEMP —-> INCREASES—> IONS VIBRATE FASTER MAKING IT HARDER FOR ELECTRONS TO PASS ALONG THE WIRE

Question 3

Diodes:

Measure the current in a circuit

Supply power to a circuit

Switch circuits on and off

Only allow current to flow one way around a circuit

Answer 3

Only allow current to flow one way around a circuit
