Question

The voltage $v(t)$ across a device and the current $i(t)$ through it are $v(t) = 14cos(2t)$ V, and $i(t) = 22(1 - e^{-0.5t})$ mA. Calculate the power consumed by the device at $t = 1$ s. The power consumed by the device at $t = 1$ s is mW.

          The voltage $v(t)$ across a device and the current $i(t)$ through it are
$v(t) = 14cos(2t)$ V, and $i(t) = 22(1 - e^{-0.5t})$ mA.
Calculate the power consumed by the device at $t = 1$ s.
The power consumed by the device at $t = 1$ s is  mW.

Step 1

Step 1: The power consumed by the device can be calculated using the formula P(t) = v(t) * i(t), where P(t) is the power at time t, v(t) is the voltage at time t, and i(t) is the current at time t. Show more…
