Question

when a 50 volt battery is connected across an unknown resistor there is a current of 150mA in circuit​

Answer 1

Answer:

$0.003 \: ohms$

Explanation:

Step 1:

Given:

Voltage = 50 volts, Current = 150mA = 150/1000 =0.150000, Resistance = ?

Step 2:

voltage = Current × Resistance

V = I R

Step 3:

From that,

Resistance = Voltage/Current

R = V/I

Step 4:

Now apply the given values,

R = 50/0.150000 = 0.003 Ohms.
