Question

2. CALCULATE ammeter reading for each ammeter,

voltmeter reading for each volt meter and equivalent

resistance, if R1 = 6 ohm, R2 = 12 ohm, R3 = 18 ohm and

voltage supplied is 24v.(4m)​

Answer 1

The ammeter will read 77A.

Explanation:

We are given that:

• The value of each resistance that is
• R1 = 6 ohm
• R2 = 12 ohm
• R3 = 18 ohm
• To find: the reading of ammeter =?

Solution:

As resistance are connected in series, therefore, total resistanec is

R1+ R2 + R3 = 1/6 + 1/12 + 1/18

R1+ R2 + R3 = 11/36 = 0.31

Now according to ohm's law, the voltage is

V = IR

I = V / R

I = 24 / 0.31

I = 77 A

Thus the ammeter will read 77A.
