Answer / satya dev ( knight frank)

By PMMC type Ammeter

Answer / kishore kumar t.n

We can use direct DC ammeter for small currents. DC Clamp
meter is used to measure the DC current also. For measuring
high DC current with DC shunt(75mv) we can use DC Ammeter
(75mv)

Answer / pratheesh

One methode is use a Clamp-on meter which is capable to
measure DC current also.

For small amount of currents(say upto 5 or 10 ampere)we can
connect one suitable range ammeter in series with the
circuit.

If the amount of current is too high( say 100s of ampere)
we can use series resistors and by measuring the voltage
drop across this resistance with a voltmeter, we can
calculate the corresponding current flow thrugh the power
cable.

Answer / jitender kotwal

WE can measure the dc current with tungtester or putting a
shunt on the negative terminal and from the shunt two
points connect the amps meter
