Question 1. A parallel plate capacitor consists of two metal plates, each of area 150 cm2 and separated by a gap 0.60 cm thick. What is its capacitance?
Question 2. Three identical capacitors are connected in a circuit as shown. If the capacitors have a value of 7.2 μF and V = 78 V, determine the total capacitance and the charge and potential difference across each resistor.
Question 3. A hair dryer draws 7.5 A when plugged into a 120-V line. (a) What is its resistance? (b) How much charge passes through it in 15 minutes? (c) What is the power rating?
Question 4. Find the total resistance RT and the current and voltage of each resistor connected in a circuit as shown in the figure.
