Electric lamp (100 Ω resistance), a toaster (50 Ω resistance), and water filter (500 Ω resistance) are parallelly connected to 220V source.

Resistance is the ratio between the applied voltage to the current flowing through a circuit. Current, on the other hand, is the flow of electrical charge carrier.

As per the given question,

R₁ = 100 Ω
R₂ = 50 Ω
R₃ = 500 Ω

Now, in order to find its resistance and current, we have to:

Thus, the total resistance= 1/R = 1/R₁ + 1/R₂ + 1/R₃

⇒ 1/R = 1/100 Ω + 1/50 Ω + 1/500 Ω

⇒ 1/R = ( 5 + 10 + 1 )/500

⇒ 1/R = 16/500

Hence, 500/16 = Total R

Total Resistance = 500/16 Ω

Since R = V/I (according to Ohm’s Law)

Therefore, after replacing the values, we get,

⇒ 500/16 = 220/I

⇒ I = 220 × 16/500

⇒ I = 7.04 A

A charged particle $+q$ in an electric field $\vec{E}$ experiences a force in the direction of the electric field. As a result, its kinetic energy changes. Similarly, the charged particle also experiences a force when it moves in a magnetic field $\vec{B}$. But this magnetic force is perpendicular to both velocity $\vec{v}$ of the charged particle and the magnetic field $\vec{B}$, so it cannot change the kinetic energy of the charged particle. Consider two charged particles 1 and 2 of masses $m$ and $\frac{m}{2}$ having charges $-q$ and $+2q$ respectively. They are accelerated from rest through the same potential difference $V$ and acquire kinetic energy $K_1$ and $K_2$. Then they enter in a region of uniform magnetic field $\vec{B}$ perpendicular to their velocities.
