Which of the following laws relates emf, potential, current, and resistance in a circuit? ohm’s law newton’s law of gravity coulomb’s law conservation of charge

Ohm's law

Explanation:

As per ohm's law we know that the potential difference across the resistance is applied then the current flows through is given by

here we know that

V = EMF or potential difference across the resistance

R = Resistance

i = electric current

So ohm's law relates the potential difference across the resistance and current flow through the resistance with the resistance of the wire

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

i would say
