How do you calculate the voltage after a resistor? Ohm’s Law states that V=I*R, where V is voltage, I is current and R is resistance. In a series circuit, the voltage drop across each resistor will be directly proportional to the size of the resistor. In a parallel circuit, the voltage drop across each resistor […]
What would be the path of reflected light if an incident ray passes through focus?
What would be the path of reflected light if an incident ray passes through focus? An incident ray passing through the focus will be reflected parallel to the principal axis. Why the light ray retraces its path when it passes through Centre of curvature? Answer: The reason for light falling on the centre of curvature […]

What is the melting point of water?
What is the melting point of water? 0 °C Why water has high boiling point and freezing point? So despite its small molecular weight, water has an incredibly big boiling point. This is because water requires more energy to break its hydrogen bonds before it can then begin to boil. The same concept is applied to […]
