Effects on current if resitance is double?
Ohm'sLaw states Voltage = Current x Resistance. Therefore, for the same voltage if you have 2 x R, you must have 1/2 x Current to get the same voltage.
When resitance increases current does what?
Current goes down with an increase in resistance.
What is a material with little resitance to electric current called?
This is called a conductor.
What is power equation with the resitance of 8.2 and current of .005?
v=ir .005X8.2=.0041
If the potential difference between two points increases what will the current do?
If the potential increase and resitance remain the same ,the current will encrease
Why is the resistance vs current graph is not linear?
resitance is inversly proportional to current when (v) is kept constant <><><><><> Because resistance is a function of temperature.
When you double the voltage in a simple electric circuityou double?
In that case, the current will also be doubled. This follows from Ohm's Law (current = voltage / resitance)
How much current flows through a circuit if the resitance is 4 ohms and there is a12 volt battery?
3 Ampere
Why can't you use a mutitester as an ohmmeter if it has no battery?
An ohmmeter works by applying a voltage, and measuring the corresponding current. This is an application of Ohm's law: resitance = voltage / current.
A current of 6A flows through a resitor with a difference of 2V?
R = E/IThe resitance of the resitor is (2/6) = 1/3rd ohm.
If resitance stays the same current increases dose the voltage increase?
Ohm's law states that the current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance of the circuit. I = E/R.
What is the si unit of resitance?
Ohm.
