Question

our 5.0 resistors are connected in series with a 9.0 V battery. Find the following. (a) the equivalent resistance of thecircuit
1

(b) the current in each resistor
2 A

(c) Repeat for the case in which all four resistors are connectedin parallel across the battery. equivalent resistance 3 current in each resistor 4 A (a) the equivalent resistance of thecircuit
1

(b) the current in each resistor
2 A

(c) Repeat for the case in which all four resistors are connectedin parallel across the battery. equivalent resistance 3 current in each resistor 4 A equivalent resistance 3 current in each resistor 4 A

Explanation / Answer

given that all four ressistor have resis tance = R =5.0 V = 9.0v when they are conneted in series =Req= 4 * 5= 20 current each ressitor = I = V/Req =9.0v/20= 0.45 A when they are connected in parallel 1/Req= 1/R1 + 1/R2 +1/R3 + 1/R4            =1/5 + 1/5 + 1/5 + 1/5 = 0.8 Req= 1/0.8 = 5 current each resistor = I = V/R1 = 9.0/5.0 =1.8 A all ressitor passing same cuurent 1.8A becausethey are equal .            =1/5 + 1/5 + 1/5 + 1/5 = 0.8 Req= 1/0.8 = 5 current each resistor = I = V/R1 = 9.0/5.0 =1.8 A all ressitor passing same cuurent 1.8A becausethey are equal .
