In the circuit below, i = 6.7 Amps, R₁ = 8.9Ω and R₂ = 5.6Ω. Find V_s in Volts to 2dp.

How many loops are there in this circuit? Express your answer as an integer.

At the node picture below, i₁ = -1 A, i₂ = 5 A and i₃ = 1 A. Find i_x in Amps.

What is the power absorbed in Watts by a resistor with resistance of 9.7Ω is connected to a voltage source of 9.2 Volts? Give your answer to 3 dp.

If i = 1A, v = 5V, the circuit element below is supplying power. True or false?

Capacitor voltage is related to capacitor current by:

where is capacitance and is time.

Capacitor voltages can change discontinuously

In an RC circuit, the voltage across the capacitor at time is the initial value plus 0.632 times the difference between the the final and initial voltage.

Electric charge does not travel between the plates of a capacitor through the dielectric.
