Question

Two resistors. A (20Ω) and B (30Ω), are connected in parallel. The combination is connected to a 3 V battery. The current through the battery is?

• A. 0.15 A
• B. 0.30 A
• C. 0.50 A
• D. 0.25 A

Answer 1

Answer:

D. 0.25 A

The current through the battery is 0.25 A.

The amount of obstruction to current passage in an electrical circuit is measured as resistance.

Ohms, a unit of measurement for resistance, are represented by the Greek letter omega (Ω).

Electrical charge carriers, often electrons or atoms with a deficiency in electrons, travel in current.

The ampere, denoted by the letter A, is the standard unit.
