Explanation

 In a capacitive circuit, the current leads the voltage. The phase difference between the two is 90°. 

Remember the relationship

A common mnemonic to remember the phase relationship in AC circuits is "ELI the ICE man": 

ELI: In an Electric circuit with an Load (inductor), the voltage (E) leads the current (I).

ICE: In a circuit with a Capacitor, the current (I) leads the voltage (E). 

Explanation

An electric circuit is a closed path through which electric current flows.

It enabling the transfer of electrical energy.

Electric current is measured in amperes using an ammeter.

Explanation

In Young's double-slit experiment, if the slit separation is halved and the screen distance is doubled,

The fringe width will become four times its original value.

This is because fringe width is directly proportional to the screen distance (D) and inversely proportional to the slit separation (d),

So halving 'd' and doubling 'D' results in a multiplication of the fringe width by 2 / (1/2) = 4. 

Explanation

• The SI unit of energy is the Joule (J).
• It is the unit of energy, work, and heat.

Explanation

Formula:

KE=1​/2mv2

Where:

• $m=$ (mass)

• $v=$ (velocity)

Step 1: Square the velocity

v^2=^52=25

Step 2: Multiply by mass

m⋅v^2=2×25=50

Step 3: Multiply by 1/2

KE=1​/2×50=25J
