ohm
This relationship was discovered by Karl Georg Ohm.
voltage depend on current and resistance r.p.m depend on no of pole
The total resistance of a circuit is the sum of the supply's internal resistance and its load resistance, because they are in series with each other. This is true regardless of the magnitude of, or the variation in, the current.
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
Ohm's law gives the relationship between current, voltage, and resistance. The law states that I=V/R, where I is current, V is voltage, and R is resistance. Source: university digital fundamentals
The current drawn from a power source is directly proportional to the voltage of thesource, and inversely proportional to the resistance of the circuit between its terminals.There is no relationship between the current and the physical size of the source.
V=IR where V is the voltage (volts), I is current (amps) and R is resistance (ohms)
Ohm's LawVolts = Current x Resistance.
A volt is the unit of measurement for electrical potential difference, while an ampere is the unit of measurement for electrical current. The relationship between them is defined by Ohm's Law, which states that voltage equals current multiplied by resistance (V = I x R). In other words, voltage is proportional to current when resistance is constant.
The relation between resistance R, Current I and voltage V is: R= V/I Therefore: 60 = 12 / I <=> I = 12 / 60 = 0.2 amp
This is because the resistance is measured by applying a fixed voltage to the resistor and measuring the current. Since I = V/R, the current/resistance relation is non-linear.
In microscopic Ohm's law, the relationship between resistance and current is that resistance is directly proportional to the current flowing through a material. This means that as resistance increases, the current flowing through the material decreases, and vice versa.
