Alpha particles have twice the charge of an electron. What is the current caused by a radioactive source which emits 3000 alpha particles per second, to 3 significant figures?

Answer :

Final answer:

The current caused by a radioactive source emitting 3000 alpha particles per second is 6000 Amps.

Explanation:

To calculate the current caused by a radioactive source emitting alpha particles, we need to know the charge and the number of particles emitted per second. Alpha particles have a charge of +2. Therefore, the current can be calculated by multiplying the charge of each particle (+2) by the number of particles emitted per second (3000):

Current = 2 x 3000 = 6000 Amps (to 3 significant figures).
