100%
A circuit made up of 6 resistors is shown in the attached image, with resistances R1 = 22 Ω, R2 = 75 Ω, R3 = 37 Ω, R4 = 74 Ω, R5 = 79 Ω and R6 = 53 Ω. The total current going through the circuit is I = 4.5 A.
Express the equivalent resistance R of the combination of R1, R2, R3, R4, R5, and R6, and use it to calculate the numerical resistance R in Ω.
Express the potential difference between a and b, ΔV, in terms of the total current I and the equivalent resistance of the entire circuit R. Then use this to calculate the numerical value of ΔV in V.
