A 63.1-2 resistor is connected in parallel with a 123.9-Q resistor. This parallel group is connected in series with a 26.7-2 resistor. The total combination is connected across a 18.1-V battery. Find (a) the current and (b) the power dissipated in the 123.9-2 resistor. R R2 V (a) Number i Units (b) Number i Units

In the figure below, determine the current in each resistor, the potential difference across the 2.00 ✕ 102 Ω resistor, and the power delivered by each battery. a) the current (in A) in each resistor I200 magnitude   I80 magnitude   I20 magnitude   I70 magnitude     b) the potential difference (in V) across the 2.00 ✕ 102 Ω resistor   c) the power (in W) delivered by each battery P40  W P360  W P80 W

When different resistors are connected in parallel across an ideal battery, we can be certain that a the same current flows in each one. b the potential difference across each is the same. c the power dissipated in each is the same. d their equivalent resistance is greater than the resistance of any one of the individual resistances. e their equivalent resistance is equal to the average of the individual resistances.
