How are current and voltage related are they directly proprtional or inversely proportional?
Current and Voltage are directly proportional. V=voltage, I=current, R=resistance V=I*R
How is power and voltage related?
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
How are voltage resistance and current related?
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
How the current are related to the power supplied by the source?
Power (watts) is voltage times current.
What is the relation between voltage and 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.
What related to voltage and current?
Resistance = Current x Voltage This is commonly written R = IV note: this means (ohm)=(coulomb/second)(volt)
According to Ohm's Law how is voltage related to resistance and 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.
What is the difference in the current and voltage?
Current (amperes) is the rate of flow of electric charge, in coulombs per second. Voltage, on the other hand, is the electric potential of that charge, in joules per coulomb.Current and voltage are related to resistance by Ohm's Law, which states that voltage is equal to current times resistance.There is a tendency to misuse the term "current", and to apply it, for instance as "an electric current of 120 volts". This usage is incorrect. Current is current, and voltage is voltage, as noted above.
How are current and voltage related to the power supplied by the source?
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
What are three related electrical factors did George Ohm investigate?
the answer is current, voltage, and resistance
What happens to the current in a circuit if a 10 ohm resistor is removed and replaced by a 20 ohm resistor?
Voltage, current, and resistance can be related by this formula. V = iR, where I is the current. Assuming that the voltage stays constant, current will decrease. Hope this helps!
How is current related to resistance in a circuit?
Ohm's law: voltage is current times resistance. Restating this; current is voltage divided by resistance, so increasing resistance would decrease current.
