Question

what current flows when a p.d. of 14.5 V is connected across a 1000 resistor​

Answer 1

Answer:

Step-by-step explanation:

using ohms law

v=ir

14.5=i(1000)

i= 14.5/1000= 0.0145 amperes

Answer 2

Step-by-step explanation:

Given: V=12 V

I=2.5 mA

Let the resistance be R

By Ohm's Law,

V=IR

12=2.5×10

−3

R

R=4.8×10

3

Ω
