Question

The graph in (Figure 1) shows the current through a 2.0 ΩΩ resistor as a function of time. Figure 1 of 1The plot shows the current as a function of time. Time is measured from 0 to 10 seconds on the x axis. Current is measured from 0 to 2.5 amperes on the y axis. First the current stays at 0 amperes from the origin until 2 seconds. Then it jumps to 2.5 amperes and remains at this value until 5 seconds. Then it drops to 1.25 amperes and stays at this value until 10 seconds.

Part A How much charge flowed through the resistor during the 10 ss interval shown? Express your answer in coulombs to two significant figures.

Part B

What was the total energy dissipated by the resistor during this time?

Express your answer in joules to two significant figures.
