Question

When a 24 V battery is connected
across an unknown resistor, there is a
current of 2.5 mA in the circuit. Find the
value of the resistance of the resistor *
O
a) 4.8 ko
O
b) 9.6 ΚΩ
O
c) 4.80
d) 9.60​

Answer 1

Answer:

hence option b is correct one

Explanation:

$Given = potential \: difference, V = 24$

$Current, I = 2.5 mA = 2.5 \times {10}^{ - 3}$

$We \: know \: that$

$V = IR$

$\frac{24}{2.5 \times {10}^{ - 3} }$

$\frac{24 \times {10}^{ 3} }{2.5}$

$\frac{24000}{25 \10 }$

$\frac{960 \1}{1 \10}$

$96000 \: ohm$

$or \: 9.6k \: ohm$
