Question

A student creates a circuit using a 10V battery, as shown in the picture below.

Answer 1

Answer:

I = 2 [amp]

Explanation:

To solve this problem we must use ohm's law, which tells us that the voltage is equal to the product of the current by the resistance.

The resistances in the diagram are connected in series, in this way the total resistance will be equal to the algebraic sum of the resistivity.

R = R1 + R2

R = 3 + 2

R = 5 [ohm]

Now, using ohm's law we have:

V = I*R

where:

V = voltage = 10 [V]

I = current [amp]

R = resistance = 5 [ohm]

I = V/R

I = 10/5

I = 2 [amp]
