Question

student wants to measure a current running through a 10 ? resistor connected to a 30V voltage source, which multimeter input should he/she use for the measurement?

Hint: Calculate the current in the circuit--the current you are trying to measure should not exceed the multimeter setting you are using.

Question 2 options:

The 2A setting on the multimeter

The 20A setting on the multimeter

The V,? input on the multimeter

None of the above

The 2A setting on the multimeter

The 20A setting on the multimeter

The V,? input on the multimeter

None of the above

Explanation / Answer

here,

R = 10 ohm

V = 30 V

Using ohm's law

,

V =IR

30 = I*10

I = 3 A

therefore , she will use The 20A setting on the multimeter
