Question

a circuit contains two 1.5 volt batteries and a bulb with a resistance of 3 ohms calculate the current​ (PLEASE ITS DUE SO SOON))

Answer 1

V=IR

1.5=3*I

I= 0.5 Ampere

Answer 2

Answer:

1 Ampere.

Explanation:

Voltage supplied by 2 batteries

= 1.5 V + 1.5 V = 3 V

Next we know a bulb is also connected in the circuit with resistance 3 ohms.

let this be R1 = 3 ohms.

Assumption:

The wire offers no resistance

There is no heat loss.

Then, you can use Ohm's Law which relates current and voltage supplied in a circuit as:

V = I R

V = voltage supplied.

I = cutrent flowing in the circuit.

R = Resistance

We already have the values :

3 V = I × 3 ohms

=> 3 V / 3 ohms = I

=> 1 V / ohm = I

=> 1 Ampere = I
