A loop circuit has a resistance of r1 and a current of 1. 9 a. 1. 7 a when an additional 3 resistor is added in series with r1. Assume the inter- nal resistance of the source of emf is zero. Let the current with r1 be i1 and the cur- rent with additional resistance r2 be i2. Then since the emf is a constant and the internal resistance of the battery is zero, we have. I1 r1 = i2 r1 + i2 r2. Four resistors are connected as shown in the gure. Find the resistance between points a and b. Ohm"s law is v = i r . A good rule of thumb is to eliminate junc- tions connected by zero resistance. Eb rashid (sar3553) hw6 dc circuits storr (37537)
