The slope of a line is the change in the vertical direction divided by the change in the horizontal direction ("rise over run"). Find the slope for each resistor on Plot 2-1. Notice that the slope has units. If the change in current is measured in mA and the change in voltage is measured in V, the slope is mA/V = mS.

Answer:
Slope for R1:
Slope for R2:
Slope for R3:

What happens to the slope of the  I-V curve for larger resistors?

Answer:



What happens to the slope of the  I-V curve for larger resistors?

a)
If the resistance is halved and the voltage is not changed, what will happen to the current in a resistive circuit?
b)
If the voltage is doubled and the resistance is not changed, what will happen to the current in a resistive circuit?
If the current in a resistive circuit is 24 mA and the applied voltage is 48 V, what is the resistance?
Answer:



What is the current through a 10 Ω resistor with 5.0 V applied?
