Resistor current

Question

Answer 1

Step 1:

Current across the resistor is .

Find the voltage  using waveform given.

Observe the graph:

Voltage in  is .

Resistance .

Substitute  and  in .

Current in  is .

Step 2:

Similarly for .

Voltage in  is .

Substitute  and  in .

Current in  is .

Therefore the current across the resistor .

Solution: 

.
