Question

According to Ohm’s law, which combination of units is the same as the unit for voltage?


ohm ÷ ampere

ampere × ohm

ohm + ampere

ampere ÷ ohm

Answer 1

For many conductors of electricity, the electric current which will flow through them is directly proportional to the voltage applied to them. When a microscopic view of Ohm's law is taken, it is found to depend upon the fact that the drift velocity of charges through the material is proportional to the electric field in the conductor. The ratio of voltage to current is called the resistance, and if the ratio is constant over a wide range of voltages, the material is said to be an "ohmic" material. If the material can be characterized by such a resistance, then the current can be predicted from the relationship:
and The voltage changes around any closed loop must sum to zero. No matter what path you take through an electric circuit, if you return to your starting point you must measure the same voltage, constraining the net change around the loop to be zero. Since voltage is electric potential energy per unit charge, the voltage law can be seen to be a consequence of conservation of energy i hope this helps u

Answer 2

In your study of electricity have you heard the term " IR deop" This is the resultant voltage drop across a resistor. The product of current and resistance. Now considering the units of those (current & resistance) select the best answer.

Answer 3

V=IR
Volt=ampere*ohm

Answer 4

*deop - drop
