Question

in the circuit shown below, the emf of the batteries are E1=42 volts, E2= 25 volts, E3=33volts and the resistors have a value of R1= 34 R2=36. initially switch s is open. After the switch is closed, how much does the current change in resistor R1. Anwer to the nearest milliamp. If the current increases after the switch is closed imput answer as positive. if i decreases input answer as negative.

U Question 2 2 pts In the circuit shown below, the emfs of the batteries are E1-41 volts, E2-20 volts, and E3-32 volts; and the resistors have values R2 - 33 and R2 - 48 2. Initially switch Sis open. After the switch is closed, how much does the current change in resistor R,? Answer to the nearest milliamp, where 1000 milliamps - 1 amp. If the current increases after the switch is closed, input your answer as a positive number. If it decreases, input your answer as a negative number.
