Ohm's law: Current is voltage divided by resistance.
50 volts divided by 5 ohms = 10 amperes.

If the voltage applied to a circuit remains constant and the resistance in the circuit is increased the current will?
V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease
How the current in a circuit changes if the voltage in the circuit is decreased and the resistance remains the same?
If the ratio of voltage to current is constant, then the circuit is obeying Ohm's Law. If the ratio changes for variations in voltage, then the circuit does not obey Ohm's Law.
When resistance decreases what happens to current?
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
What happens to the voltage if the current increases?
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.
How does electrical resistance change the current in a circuit?
Electrical resistance is opposition to electric current flow. There is a resistance to the flow of current. And a "balance" between applied voltage and resistance determines how much current will flow in a circuit. For a given applied voltage, if we increase the resistance, the current flow will decrease. For that same applied voltage, if we decrease the resistance, the current flow will increase. It's a simple relationship, and it is set down by the following expression: E = I x R We can also write it as I = E / R and R = E / I Voltage (in volts) is E, current (in amps) is I, and resistance (in ohms) is R. In the first expression, voltage is equal to current times resistance. For a constant voltage, any increase in resistance will cause a decrease in current flow. And any decrease in resistance will cause in increase in current flow. Just as cited earlier.
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
How do you figure out how much current is in an electrical wire?
If you know the voltage and resistance, then current = voltage divided by resistance. Otherwise, you can attach an ammeter into the circuit (in series).
What is a relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What increases when the resistance of an electrical circuit decreases?
Current increases if the voltage remains constant.
What is the term for the relationship of voltage current and resistance in simple electrical circuit?
Ohms Law
What instrument measures electrical earth resistance?
A multimeter device can measure resistance, current, AC/DC voltage, and it also can determine continuity on an electrical circuit, and its range for current, voltage and resistance is widely variable.
What is an equation for power?
Power = (energy used)/(time to use it)Power dissipated by an electrical circuit =(voltage across the circuit) x (current through the circuit)or(resistance of the circuit) x (square of the current through the circuit)or(square of the voltage across the circuit)/(resistance of the circuit)
What will happen in a circuit if the voltage does not change but the resistance in the circuit increases?
If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
What does resistance in an electrical circuit mean?
i dont know really, thats why im asking right
What happen to current in a circuit if the voltage in not charged but the resistant is double?
In an electrical circuit, if resistance is doubled, EMF (measured in volts) stays constant, and current is halved.
