Resistor current

Question

Answer 1

Step 1 :

Current across resistor is .

Find the voltage using waveform given.

Observe the graph:

Two points in the interval are (0, 0) and (2, 10).

Two points in the interval are (2, 10) and (4, 10).

Find the voltage in .

Slope = .

Point-slope form of the equation is .

Slope = 5 and the point is (0, 0).

Voltage in is .

Resistance .

Substitute and in .

Current in is .

Step 2 :

Similarly for .

Slope = .

Slope =0 and the point is (2, 10).

Voltage in is .

Substitute and in .

Therefore the current across resistor is .

Solution :

.
