A 25 W and a 100 W bulbs are joined in parallel and connected to A.C. mains. Which will glow brighter?

A 60W-220V bulb and 100W-220V bulb are connected in parallel to main supply. Which bulb will draw more current?

In an electrical circuit three incandescent bulbs A, B and C of rating 40 W, 60 W and 100 W respectively are connected in parallel to an electric source. Which of the following is likely to happen regarding their brightness?

A 50 W bulb is connected in parallel with a room heater, is connected across that mains. If 50 W bulb is now replaced by 150 W bulb in each of the two cases, will the heat produced by heater by smaller, remain the same or be larger?

Two lamps, one rated 100 W at 220 V and other 60 W at 220 V, are connected in parallel to electric main supply. What current is drawn from the line if the supply voltage is 220 V?

Three 60 W incandescent buolbs are connected in a parallel. Calculate the total power consumed.

A 50 W bulb is connected in series with a room heater, is connected across that mains. If 50 W bulb is now replaced by 150 W bulb in each of the two cases, will the heat produced by heater by smaller, remain the same or be larger?

An capacitor C, a variable resistor R and a bulb B are connected in series to the ac mains in circuits as shown in Fig. The bulb glows with some brightness. How will the glow of the bulb change if the resistance R is increased keeping the same capacitance.
