Answer:

False

Explanation:

The magnitude of electric charge carried by an electron as well as proton is called elementary charge. Both the electron and proton have the same charge but the difference is that the electrons are negatively charged species and the protons are positively charged.

The elementary charge is equal to 1.6\times 10^{-19}\ C. Hence, the given statement "The elementary charge equals 1.6\times 10^{-9}\ C" is false.

How much current will pass through a 12.5 ohm resistor when it is connected to ta 115 volt source of electrical potential?
Marrrta [24]

Answer:

9.2 amperes

Explanation:

Ohm's law states that the voltage V across a conductor of resistance R is given by V = R I

Here, voltage V is proportional to the current I.

For voltage, unit is volts (V)

For current, unit is amperes (A)

For resistance, unit is Ohms (Ω)

Put R = 12.5 and V = 115 in V=RI

115=12.5I\\I=\frac{115}{12.5}\\ =9.2\,\,amperes
