Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship: =, where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in...
Ohms Law can be stated mathematically as: I = E/R Where: I is the current, E is the voltage, R is the resistance As you can see from the above formula, if the voltage were to double, then so would ...
Ohm's Law defines the relationships between (P) power, (E) voltage, (I) current, and (R) resistance. One ohm is the resistance value through which one volt will maintain a current of one ampere.

According to this law the potential difference (voltage) across an ideal conductor is proportional to the current flowing through it. This law can be given as V = IR Where ‘R’ is a constant of proportionality called as ‘résistance. Its unit is ohms. V = potential difference between two points. Its unit is volts. I = Current flowing ...
Ohms Law Wheel; Ohm's law (named after the German physicist Georg Ohm) defines the relationship between Voltage, Current and Resistance. V = I x R. Where: V is the electrical potential (voltage), measured in volts (V), I is the current, measured in Amperes (Amps/A), and; R is the resistance, measured in Ohms (Ω).
Ohm’s Law Memory Aid : Ohm’s Law Memory Aid To calculate one unit of electricity when the other two are known, simply use your finger and cover the unit you do not know. For example, if both voltage (V) and resistance (R) are known, cover the letter/(amperes).
Ohm’s Law also makes intuitive sense if you apply it to the water-and-pipe analogy. If we have a water pump that exerts pressure (voltage) to push water around a “circuit” (current) through a restriction (resistance), we can model how the three variables interrelate. If the resistance to water ...
Ohm's law [ōmz] a mathematical relationship formulated by the German physicist Georg Simon Ohm in 1826, comparing voltage (V), current (I), and resistance (R), usable for either alternating current or direct current. It originally applied only to situations of steady direct current, with the formula V = IR; with alternating current, the electrical ...

In a circuit, voltage and current are (a) directly proportional, (b) inversely proportional, (c) not proportional. According to Ohm’s Law, what effect will cutting the resistance have on the current? If the voltage stays the same and the resistance is ¼ of its original, what will happen to the current?
