Many people find the following analogy useful. Instead of a wire, think of a garden hose. Instead of current, think of water flowing through the hose. Instead of voltage, think of water pressure. And instead of resistance, think of either a crimp in the hose or a narrow section of hose that restricts water flow. After you get your brain around that idea, consider Ohm's Law, which is the most fundamental rule in the study of electricity. Ohm's Law is simply: V = IR, where V = voltage, I = current, and R = resistance. Ohm's Law can be stated in two other ways: I = V/R and R = V/I.
Resistance is ability of substance to oppose the electron flowing through itself. This oppostd energy will be lost in the form of heat. R'l b constant until temp n presr constant. Voltage n currents r parameters of applied input power(el' energy). V*I=P voltage makes this able to draw current as per ohms law. We r al doing this to draw current for diffent applications(load).
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
Current, voltage and resistance are related by the Ohm's law formula which states that current is directly proportional to the applied voltage and inversely proportional to the resistance at a constant temperature. Stated mathematically: I = E/R where I = current in amperes, abbreviated to A E = voltage in volts, abbreviated to V R = resistance in ohms, usually signified by the Greek omega Ω
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
It is halved. coz voltage=current * resistance
Ohm's Law Voltage = Current x Resistance
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
Voltage = Current * Resistance (Ohm's law)
No. Voltage divided by resistance is equal to current.
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
Ohm's Law Voltage = Current x Resistance Current = Voltage divided by Resistance Resistance = Voltage divided by Current
The current will be zero if there is no voltage.
Current, voltage and resistance are related by the Ohm's law formula which states that current is directly proportional to the applied voltage and inversely proportional to the resistance at a constant temperature. Stated mathematically: I = E/R where I = current in amperes, abbreviated to A E = voltage in volts, abbreviated to V R = resistance in ohms, usually signified by the Greek omega Ω
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
1). Voltage = (resistance) x (current)2). Current = (voltage) / (resistance)3). Resistance = (voltage) / (current)I think #2 is Ohm's original statement, but any one of these can be massaged algebraicallyin order to derive the other two.
