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.
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.
If the resistance of a load increases will the current increase or decrease?
it increases because increasing load means more output power, more output power means more current
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 will adding resistance to series circuit cause?
A decrease in current.
How does the increasing the resistance affect the current?
Increasing resistance decreases current.

How does load current vary with the load resistance?
Their relationship is only dependent on the voltage lost across that resistor; voltage equals resistance times current, so increasing the current for a given voltage will require a decrease in the resistance, and vice versa.
How does a resister change the current in a circuit?
Resistance is the ratio of voltage to current. If you increase the resistance while maintaining the same voltage, then the current will decrease, and vice-versa.
If the resistance of a load increases will the current increase or decrease?
it increases because increasing load means more output power, more output power means more current
Effect on voltage as current increases through constant resistance?
If the current is held constant, the voltage will decrease.

Why doesn't current decrease in series resistance circuit though resistance opposes current?
If you add another resistor or just increase the resistance the current will decrease. I think the statement you are talking about means that whatever the current is in the series circuit it will be the same everywhere in that circuit, on both sides of the resistance. The resistance lowers the current in the entire circuit, not just after the resistance.
Would increasing the resistance increase electric current?
no
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.
