What is the relationship between resistance and current for a given voltage?
Ohm's Law states that the relationship between resistance, current, and voltage is given by the equation V IR, where V is the voltage, I is the current, and R is the resistance. This means that for a given voltage, the current flowing through a circuit is inversely proportional to the resistance - as resistance increases, current decreases, and vice versa.
What is the formula for calculating current in a circuit when given the values of power and resistance, where i p/a?
The formula for calculating current in a circuit when given the values of power and resistance is i p/a.
What is the current in a circuit that has a resistance of 30 ohms and a power of 2 watts?
To find the current in the circuit, you can use the formula: Power = Current^2 * Resistance. Given the values, you can rearrange the formula to solve for current: Current = sqrt(Power / Resistance). Plugging in the values, you get Current = sqrt(2 / 30) which simplifies to approximately 0.27 amperes.
How do you find resistance by a graph?
To find resistance from a graph of voltage vs. current, you can calculate the slope of the graph. Resistance is equal to the slope, so you can divide the voltage by the current to determine the resistance. The unit of resistance is ohms (Ω).
What is the maximum voltage formula for a circuit with a given resistance and current?
The maximum voltage formula for a circuit is V I R, where V is the voltage, I is the current, and R is the resistance.
How do you compute for voltage if current and resistance is given?
Voltage = Current * Resistance (Ohm's law)

How does resistance after current?
Assuming you are asking "How does resistance altercurrent?", then the answer is that, for a given value of potential difference, the current is inversely-proportional to the resistance. E.g. doubling the resistance will reduce the current by half.
What formula to find the emf and internal resistance for cell when given the current and the voltage?
I don't think you can do that, with the information provided.
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.

How do i find the current?
Current= Volage/Resistance
The voltage in a lightbulb is given by the equation V IR. In this equation V is the voltage I is the current and R is the resistance. What is the current in a lightbulb with a voltage of 10.0 V and a?
To find the current in a lightbulb using the equation ( V = IR ), you can rearrange it to ( I = \frac{V}{R} ). If the voltage ( V ) is 10.0 V, you would need the resistance ( R ) value to calculate the current ( I ). Once you have the resistance, simply divide 10.0 V by that resistance to find the current in amps.
What is the formula to find the current of something?
The formula to find the current (I) of an electrical circuit is given by Ohm's Law, which states that current equals voltage (V) divided by resistance (R). Mathematically, it is expressed as ( I = \frac{V}{R} ). Here, current is measured in amperes (A), voltage in volts (V), and resistance in ohms (Ω).
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 is the voltage if the current is 0.4 A and the resistance is 3?
To find the voltage, you can use Ohm's Law, which states that Voltage (V) = Current (I) × Resistance (R). Given a current of 0.4 A and a resistance of 3 ohms, the voltage would be V = 0.4 A × 3 Ω = 1.2 volts. Therefore, the voltage is 1.2 volts.
