A resistance that doesn't change.
V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease
First, this statement stands as long as voltage is constant. If you held the current constant then power would increase as resistance increases.V=IR. For a fixed voltage if you increase the resistance (R) then the current (I) will decrease - following the formula.Power = VI so as the resistance increases the value of VI (power) decreases as V is constant and I gets smaller.Therefore the power is decreasing as the resistance increases (when voltage is held constant).Hope this helps.
If you are referring to a simple circuit, you could add resistance throughout it. Increased resistance means decreased current flow yet the same voltage.
ohm
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.
Time constant in an RC filter is resistance times capacitance. With ideal components, if the resistance is zero, then the time constant is zero, not mattter what the capacitance is. In a practical circuit, there is always some resistance in the conductors and in the capacitor so, if the resistance is (close to) zero, the time constant will be (close to) zero.
If measuring resistance of materials or resistors by themselves(not soldered into a circuit board) resistance is constant. If measuring resistance of a circuit then it could fluctuate with the components functioning in the circuit.
constant resistance variable resistance and accomodating resistance
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
Inversely. As resistance increases, current dereases; given that the applied voltage is constant.
Ohm's Law states: V = IR, where V is voltage, I is current and R is resistance. If the voltage is constant, then current is inversely proportional to the resistance.
If resistance is halved while voltage remains constant, the current will double.
It is halved. coz voltage=current * resistance
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
Voltage will be constant. Resistance is dependent on the components in the circuit. Source: Electronics Technician for the US Govt
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
Cell constant(C) = Resistance(R) X Specific Conductivity(K)
