What is the current when a 9 V battery is attached to a 10 ohm resistor?

If you work this out, the current is 9V/(11.5 ohms) = 0.783A, so the voltage across the 10 ohm resistor must be 7.83V.

What is the current through a 5.0 ohm resistor if the voltage across it is 10 V?

Explanation: 10/5= 2 Current =2 amperes.

How do you calculate current through a resistor?

The current through the circuit is the same for each resistor in a series circuit and is equal to the applied voltage divided by the equivalent resistance: I=VRS=9V90Ω=0.1A.

What equation would you use for current?

We can use the definition of current in the equation I = ΔQ/Δt to find the current in part (a), since charge and time are given.

What is the current through the 5.0 ohm resistor?

2.4 amperes
The current through the 5-ohm resistor is 2.4 amperes.

What is the current through 5 ohm resistance?

Current = 2 amphere.

How do you calculate current load?

Calculating Load

1. Add together the wattage capacity of all general lighting branch circuits.
2. Add in the wattage rating of all plug-in outlet circuits.
3. Add in the wattage rating of all permanent appliances (ranges, dryers, water heaters, etc.)
4. Subtract 10,000.
5. Multiply this number by .
6. Add 10,000.

How do you find the voltage applied across a 15K resistor?

[Voltage (V) = Current (I) x Resistance (R)] V (volts) = I (amps) x R (Ω) Find the voltage applied across 15 kΩ resistors when 10 mA current flows through it. Solution: Voltage (volts) = Current (amps) x Resistance (Ω); V = 10 mA x 15 kΩ; V = 150 V

How to calculate current and resistance of a resistor?

[Current (I) = Voltage (V) ÷ Resistance (R) ] I (amps) = V (volts) ÷ R (Ω) Find the current flowing through a 3 Ω resistor when a potential difference of 30 V is applied across it. Solution: Current (I) = V ÷ R; I = 30 V ÷ 3 Ω; I = 10 A How To Calculate Resistance?

What is the voltage drop across a resistive device?

Then, by applying Ohm’s law, the resistor will offer a voltage drop across a resistive device and it is given as: V(drop) = I × R where, I = current through the resistor in (A) ampere R = resistance in (Ω) ohms

How do you find the voltage drop in a circuit?

Find the current flowing through a resistor, then multiply the current in amps by resistance in ohms to find the voltage drop in volts. A circuit having combinations of resistors in series and parallel will be more complicated to deal with, though Ohm’s Law still applies.
