Step 1 :

Current across resistor is image.

Find the voltage image using waveform given.

image

Observe the graph:

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

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

Find the voltage image in image.

Slope = image.

Point-slope form of the equation is .

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

image

Voltage in image is image.

Resistance image.

Substitute image and image in image.

image

Current in image is image.

Step 2 :

Similarly for image.

Slope = image.

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

image

Voltage in image is image.

Substitute image and image in image.

image

Therefore the current across resistor is image.

Solution :

image.
