Question

symbolic form for each part The four V battery as shown in the to connect 2. For this question please first write the values in identical resistors with resistance 650 are connected across an 8.50(b) If you are to conned figure below. (a) What is the equivalent resistance for this circuit? (b) IT yoa ammeter right after battery, what value it would read? (c) What is the p What is the potential across R3? (e) Calculate the current through eacn are related one to another? resistor. How the currents R.

Explanation / Answer

(A) R2, R3 and R4 are in parallel,

1/R = 1/R2 + 1/R3 + 1/R4

R = 6.50/3 ohm

R1 and R are in series,

Req = R1 + R = 8.67 ohm

(b) I = V / Req = 8.50 / 8.67

I =0.981 A  

(C) V1 = I R1 = 6.375 Volt

(d) V3 = e - V1 = 2.125 Volt

(e) I1 = I = 0.981 A  

I2 = I3 = I4 = 2.125 / 6.50 = 0.327 A  

I1 = I2 + I3 + I4 ( KCL)
