For the circuit in the figure below, find the following. (Take E = 5.9 V, R = 5.4 ohm, and r = 1.1 ohm.)   (a) the magnitude of the current and the direction of positive current magnitude   direction     (b) the potential difference across the battery terminals a and b (c) the rate at which heat is being produced in the 5.4 ohm resistor (d) the rate at which heat is being produced inside the battery (e) the rate at which the battery's chemical energy is being used

Calculate the current in the resistor R4, given that R = 42 ohm and battery EMF = 9. (Ignore internal resistance of the batter). Write your answer in amperes.

Consider the circuit shown in the figure below. (Assume R = 4.80 Ω and ΔV = 12.0 V.) (a) Find the equivalent resistance of the circuit in the figure. I FOUND IT TO BE 12.11 OHMS(b) Find each current in the circuit.(c) Find the potential difference across each resistor.(d) Find the power dissipated by each resistor.

The figure below shows five resistors and two batteries connected in a circuit. What are the currents I,, I2, and I3? (Consider the following values: R, = 1.08 0, R2 = 2.20 0, R3 = 3.18 0, R4 = 4.04 0, R5 = 6.06 0. Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign. Indicate the direction with the sign of your answer.)
