Does the current ina circuit increase with increase in temperature?
Resistance increases as temperature increases. If Voltage is held constant then according to Ohm's Law Voltage = Current x Resistance then current would decrease as resistance increases.
If pressure is constant and current increases the resistance?
I assume you meant pressure to voltage. The resistance of a conductor is directly proportional to the temperature of the conductor. If the temperature of the conductor increases due to increased current, then the resistance tend to increase too.
What is the voltage across diode carrying a constant current?
increases
How current increases when the load increases in a generator?
Power is voltage times current. If you want to maintain constant voltage and yet increase power, then current must increase. Its simple math.
What happens to the voltage if the current increases?
Yes, if the resistance remains constant. Power is voltage times current, and current is voltage divided by resistance, so power is voltage squared divided by resistance. In essence, the power increases as the square of the voltage.

How does current vary with the resistance in the circuit if the voltage is constant?
Inversely. As resistance increases, current dereases; given that the applied voltage is constant.

What increases when the resistance of an electrical circuit decreases?
Current increases if the voltage remains constant.
What happens to electrical current and voltage in a parallel circuit as you add more bulbs?
Voltage remains constant; current increases.
How current increases when the load increases in a generator?
Power is voltage times current. If you want to maintain constant voltage and yet increase power, then current must increase. Its simple math.
What happen to the current when the voltage increased if the resistance are constant?
If voltage increases when current remains constant then resistance must also increase. Ohm's Law: Voltage = Current times Resistance.
What happens to the power in a circuit as the current increases?
P=VI If current (I) increases then P will increase proportionally. That is, assuming that voltage (V) remains constant. If voltage decreases and current increases or vice versa, proportionally then P will remain the same.
What happens to the voltage if the current increases?
Yes, if the resistance remains constant. Power is voltage times current, and current is voltage divided by resistance, so power is voltage squared divided by resistance. In essence, the power increases as the square of the voltage.
An increase in temperature will the attenuation of a cable?
Basically we should also keep in mind knowledge about voltage and current. If we keep voltage constant then by increase in temperature also increase the attenuation, if we keep current constant then attenuation drops by increasing temperature.
Can you connect batteries in series and parallel?
Yes, series and parallel connection of batteries is possible. When connected in series Voltage increases. In parallel, Current increases but voltage is constant.
