**how to calculate voltage drop without knowing the current**

3/10/2013 · Find out why Close. Resistors (2 of 11) in Parallel, Calculating Voltage, Resistance and Current Calculating Voltage, Resistance and Current Step-by-Step Science. Loading... Unsubscribe from... If not, you can find the current by dividing the voltage by the resistance. Once you have the current, just multiply it by the voltage. Once you have the current, just multiply it by the voltage. To clear things up, lets look at the above spreadsheet.

**How to find the voltage without current density**

Voltage attempts to make a current flow, and current will flow if the circuit is complete. Voltage is sometimes described as the 'push' or 'force' of the electricity, it isn't really a force but this may help you to imagine what is happening. It is possible to have voltage without current, but current cannot flow without voltage.... About your circuit... I have to know what is inside the box to say what the voltage across its terminals is. Lets suppose that there is a resistor R = 5 ohm inside the box.

**Voltage without knowing current Physics Forums**

Hello everyone, I am working on diffuse double layer with charge system. I use 1D model to simulate the electrode/electrolyte interface which similar to the COMSOL example. how to finish inside of wood drawers Formula to calculate power, current and voltage in three-phase wiring (unbalanced load, different loads on each of three phases) : Pt=P1+P2+P3 P1=V*I1*cosφ1

**How to find the voltage without current density**

Also, you may need to find from the PV module manufacturer what the coefficient of temperature for voltage is so you can calculate how the array voltage will change based on the temperature range for your install location. Depending on this install location, it is possible that the array would get into that voltage range of 115-145V. how to find the theme of a story Now we can calculate the value of the emitter current, Ie, in the circuit: Example Using the example of the values for the resistors and the voltage, Vcc, above, we're going to solve for I eq .

## How To Find Voltage Without Current

Find the current passing through the voltage source: a) b) Solution a) The voltage source is in series with the current source. Since by definition a current source keeps the current passing through itself constant and the voltage source is in series with the current source, it should have the same current .

- Hey, if the’re standard LEDs they probably have around 2V voltage drop. If you’re using a 9V battery you can try 330 Ohm. Here’s how to calculate it: If you’re using a 9V battery you can try 330 Ohm.

- Here voltage drop for 70 Sq.mm Cable (5.8 %) is higher than define voltage drop (5%) so either select higher size of cable or increase no of cable runs. If we select 2 runs, than voltage drop is 2.8% which is within limit (5%) but to use 2 runs of cable of 70 Sq.mm cable is not economical, so it’s
- By Cathleen Shamieh . To figure out how much voltage is dropped across each resistor, you use Ohm’s Law for each individual resistor. You know the value of each resistor, and you know the current flowing through each resistor.
