Step1:

\

Circuit current is $\"\"$ .

\

Find the voltage $\"\"$ using waveform given.

\

$\"\"$

\

Observe the graph:

\

Two points in the interval $\"\"$ are $\"\"$ and $\"\"$ .

\

Two points in the interval $\"\"$ are $\"\"$ and $\"\"$ .

\

Find the voltage $\"\"$ in $\"\"$ .

\

Slope = $\"\"$

\

Slope point form of the equation is $\"\"$ .

\

Slope = 20 and the point is $\"\"$ .

\

$\"\"$

\

Voltage in $\"\"$ is $\"\"$ .

\

Step 2:

\

Similarlly for $\"\"$ .

\

\

Slope = $\"\"$ .

\

Slope = -20 and the point is $\"\"$ .

\

$\"\"$

\

Voltage in $\"\"$ is $\"\"$ .

\

Find the circuit current is $\"\"$ .

\

Resistance $\"\"$ .

\

Circuit current in $\"\"$ : $\"\"$

\

Circuit current in $\"\"$ : $\"\"$

\

Therefore the circuit current is

\

$\"\"$
