A certain parallel circuit coornsists of onrely 1/2 W resistors each having the same resistance. The total resistance is 1 k ohm and the total current is 50mA. If each resistor is operating at one-half its maximum power level, determine the following:
or
(a) the number of resistors
(b) the value of each resistor
(c) the current in each branch
(d) the applied voltage
