1. Determine the total charge entering a terminal between t=1 and t=2s if the current passing the terminal is i= (3t2-t)A.

2. An energy source forces a constant current of 2 A for 10 s to flow through a light bulb. If 2.3 kj given off in the form of light and heat energy, calculate the voltage drop across the bulb.

3. Find the power delivered to an element at t=3ms if the current entering its positive terminal is
i= 5 cos 60 ∏ tA

and the voltage is:

(a) v=3i,

(b)= di/dt.
