When you increase voltage (V) then, to get the same total power (W), the current (I) must be decreased. This result comes from the Power Law:
Power = voltage x current
Ohms Law does not deal with power at all, it deals only with the relationship between voltage, resistance and current:
Voltage = resistance x current
If the current through a pure metallic conductor causes the temperature of that conductor to rise, then its resistance will increase. A practical example of this is an electric lamp. The cold resistance of a lamp is very much lower than the hot resistance.
Voltage divided by total resistance will give the current. The resistance is simply the sum of all the individual resistances.
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)
Yes In parallel circuit , current entering into the circuit will be divided intodifferent paths ( resistances) . Amount of current flow depends upon the magnitude of resistance applied in the circuit. Total current after passing through the circuit will be the sum of all current through each resistance.
If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
Yes, if the resistance remains constant. Power is voltage times current, and current is voltage divided by resistance, so power is voltage squared divided by resistance. In essence, the power increases as the square of the voltage.
Based on the simplest Electrical Equation V = I * R,(reads: voltage equals current multiplied by resistance)then, rearranged I = V / R .As resistance decreases, current flow proportionately increases
If the current through a pure metallic conductor causes the temperature of that conductor to rise, then its resistance will increase. A practical example of this is an electric lamp. The cold resistance of a lamp is very much lower than the hot resistance.
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
Ohm's Law says Voltage = Current x Resistance With constant voltage, an increase in resistance decreases the current. Now the load can be added in two basic ways. If the load is added in series the resistance will increase. If you add load in parallel the resistance will decrease and the current will increase from the source.
No.
Voltage divided by total resistance will give the current. The resistance is simply the sum of all the individual resistances.
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
A: assuming a infinite current source the current will increase accordingly
