A galvanometer of resistance 100Ω gives full scale deflection with 5mA current.To convert it into a 5 volt range voltmeter,the value of resistance connected in series is

Four bulbs each marked 40 W. 250 V are connected in series with 250 V source. The total power output is

An electrical meter of internal resistance 20Ω gives full scale deflection when one milliampere current flows through it.The maximum current that can be measured by using three resistors of resistance 12Ω each,in milliamperes is

Two wires of same material and same length have their resistances in the ratio 5:7.The ratio of the masses of the wires is

In a thermo couple the cold junction is at 30^{0}C.The temperature of inversion is found to be 540^{0}C,Then the neutral temperature is
