Problem 57

Four identical resistors are connected to a battery as shown in Figure 2134. When the switch is open, the current through the battery is . (a) When the switch is closed, will the current through the battery increase, decrease, or stay the same? Explain. (b) Calculate the current that ows through the battery when the switch is closed. Give your answer in terms of .

Step-by-Step Solution:

Q: Four identical resistors are connected to a battery as shown in Figure 21-34. When theswitch is open, the current through the battery is I0 .(a) When the switch is closed, will the current through the battery increase, decrease, or staythe same Explain.(b) Calculate the current that flows through the battery when the switch is closed. Give youranswer in terms of I0. Step-by-step solution Step 1 of 7The current through the battery I is cal0lated using the following formula: 0 = R eqHere, is the emf of the battery and R eq is the equivalent resistance.In order to find the resultant resistance, use the following rules:If the resistors R , R , R ,... are connected in series, the resultant resistance is as follows: 1 2 3 R = R1 R 2R 3..If the resistors R 1R2 R3,... are connected in parallel, the resultant resistance is as follows: R = 1 + 1 + 1 + ... -1 ( R1 R3 R 3 )
