A torch bulb rated `4.5 W, 1.5 V` is connected as shown in Fig. 7.35. The emf of the cell needed to make the bulb glow at full intensity is

Atorch bulb rated is 4.5W1.5V is connected as shwon in the figure. The emc (in V ) of the cell needed to make the bulb glow at full intensity is:

A torch bulb is rated 5 V and 500 mA. Calculate Its Power

A bulb rated 60 W-120 V is connected to 80 V mains. What is the current through the bulb

A torch bulb is rated 5 V and 500 mA. Calculate its power?

An electric bulb rated 22V is connected to 220 V-5Hz source. Then, the bulb

An electric bulb rated '220 V, 60 W' glows when connected with 220 V mains. Find the resistance of the filament of the bulb.

A torch bulb is rated 5 V and 500 mA. Calculate Its Resistances

A torch bulb is rated 5 V and 500 mA. Calculate resistance?

An electric bulb with rating 200 W, 50V is connected to a source of 120 V. A resistance R is connected in series to the bulb, so that the bulb delivers 200W . Calculate the value of R.
