In Fig. , the battery has negligible internal resistance and E = 48.0 V. R1 = R2 = 4.00 Ω and R4 = 3.00 Ω. What must the resistance R3 be for the resistor network to dissipate electrical energy at a rate of 295 W?
If two resistors with resistances R1 and R2 are connected in parallel, then the total resistance R, measured in ohms (Ω), is given by 1/R =1/R1 + 1/R2.
If R1 and R2 are increasing at rates of 0.3 Ω/s and 0.2 Ω/s, respectively, how fast (in Ω/s) is R changing when R1 = 80 Ω and R2 = 100 Ω?
When resistors 1 and 2 are connected in series, the equivalent resistanceis 15.4 Ω. When they are connected in parallel, the equivalent resistanceis 2.70 Ω. What are (a) the smaller resistance and (b) the largerresistance of these two resistors?
