To increase the resistance in a circuit one can add a resistor ( they are rated by ohms usually marked on them ) or wire the circuit in series rather than parallel. When wiring in series you double the resistance. Maybe a small voltage regulator would protect your circuit, usually done by wiring a diode in parallel reverse with it.
by using a variable resistor. We can increase and decrease the resistance in a circuit.
The resistance can be changed in following two ways:
1.By change the length of the wire.
2.By changing the area of cross section of the wire.
There are various ways: add a potentiometer; add actual resistors or add more bulbs or higher voltage bulbs.

What will happen to the resistance if the length of the conductor increase?
ERMM THE RESISTANCE INCREASES ) when longer
When tempratere increase resistance increase and when resistance increase current decrease why?
That's what "resistance" is all about: reducing the current for a given voltage. In fact, you can DEFINE resistance as voltage divided by current.
Should you increase voltage or resistance to increase flow in a circuit?
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
Does lowering resistance increase current?
Current is proportionally inverse to resistance and when the voltage is fixed, lowering resistance will increase the current
An electric heater is stretched to increase its length by 25 percent what is the increase in resistance?
The resistance of the electric heater will increase by approximately 56.25% (25% increase in length results in a 56.25% increase in resistance). This relationship is given by the formula: new resistance = (1 + 0.25)^2.
What does it mean to increase the host's resistance?
To transmitted the increase
Will the resistance of a copper conductor decrease with an increase in the applied voltage?
If all environmental conditions remain constant then the resistance will not change appreciably with applied voltage, but the current will increase. An increase in current will raise the temperature of the conductor which will increase the resistance somewhat.
What are two ways to increase air resistance of an object?
Increasing the surface area of the object, such as by adding flaps or a parachute, can increase air resistance. Additionally, increasing the object's speed will also increase the air resistance acting on it.
How do you decrease voltage?
Increase resistance
Name two factors that increase peripheral resistance?
Peripheral resistance can be increased by an increase in blood volume and the constricting of blood vessels.
If the current increases what happens to resistance?
An increase in current will only affect resistance if it causes the temperature of the conductor to change. For pure metallic conductors, and increase in temperature will cause an increase in resistance.
Will increasing the conductor thickness increase resistance?
No. A thicker conductor will lower resistance.
