Two resistors are connected in series across a 24 V supply and a current of 3 A
in the circuit. If one of the resistors has a resistance of 2 determine (a) the
value of the other resistor, and (b) the p.d. across the 2 resistor. If the circuit is
connected for 50 hours, how much energy is used?
please answer!please!

V = 24 V
I = 3 A
R 1 = 2 Ohm
V = IR
24 = 3 × 2 × R 2
24/6 = R 2
R 2 = 4 Ohm
ENERGY = I SQUARE RT
E = 3 SQUARE × 6 × 50
E = 2700 W

Answer:
(a). R2 = 8 OHM
(b). V = 12 V
(c). E = 2700W
Explanation:
V=IR, 24= 3 x R
(a). R= V/I, 24/3 = 8 ohm
Req.= 2+8 = 10 ohm
(b). V = IR
V = 3 x 8
= 24 Volts.
E = I²RT
(3)² x 8 x 50
9 x 8 x 50
= 3,600 WaTT
