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 algebraically
in order to derive the other two.
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Ohm's law states that "The current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance in the circuit." <<>> if resistor exists, resistance decreases according to ohm's law, current is directly proportional to voltage and current is inversely proportional to resistance it means as current increases, voltage increases. resistance increases, current decreases so as voltage if there is no resistor, there should be no resistance except internal resistance of voltmeter and ammeter
Ohm's Law: Current = Voltage times resistance, hence current is directly proportional to voltage.
V=IR, voltage is directly propostional to current and resistance (by ohm's law).CommentVoltage is not 'proportional to resistance'. Resistance is a constant, and is not affected by voltage at all.
Ohm's Law states Voltage = Current x Resistance. Hence if voltage is increased and resistance is constant, current will increase proportionally to the rise in 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
In an electrical circuit, resistance and voltage are directly related. According to Ohm's Law, voltage is equal to the product of resistance and current. This means that as resistance increases, voltage also increases, and vice versa.
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Current and voltage are directly proportional according to Ohm's Law. This means that as voltage increases, current increases proportionally, and as voltage decreases, current decreases proportionally. Mathematically, this relationship is expressed as I = V/R, where I is current, V is voltage, and R is resistance.
There is an inverse proportion between voltage and resistance according to Ohm's Law: V = IR, where V is voltage, I is current, and R is resistance. This means that as resistance increases, the voltage across the circuit decreases, and vice versa.
Ohm's law: voltage is current times resistance. Restating this; current is voltage divided by resistance, so increasing resistance would decrease current.
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Voltage and current are two different things. Voltage is the electric potential difference between two points. Expressed in volts, it is also joules per coulomb. Current is the charge flow past a point. Expressed in amperes, it is also coulombs per second. You can relate voltage and current using Ohm's Law, which states that voltage is equal to current times resistance. Resistance is, therefore, equal to voltage divided by current. Using base units, resistance is equal to joules per coulomb divided by coulombs per second, which simplifies to joule-seconds per coulomb squared. That is a difficult unit to write, so we just use ohms as the unit.
In an electrical circuit, current is the flow of electric charge, voltage is the force that drives the current, and resistance is the opposition to the flow of current. According to Ohm's Law, the relationship between current (I), voltage (V), and resistance (R) is given by the equation V I R, where voltage equals current multiplied by resistance.
In an electrical circuit, current is directly proportional to voltage and inversely proportional to resistance. This relationship is described by Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R), or I V/R.
