Does resistance depend upon current?
The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.
What does the size of a current depend upon?
One way to determine current is to measure it, with an ammeter. Another way is to calculate it using Ohm's law: current = voltage / resistance.
What would the current flow be if a short circuit is put across the battery's terminals?
That will depend on the internal resistance of the battery. I = E / R Where I is the current, E is the open circuit battery voltage, and R is the internal resistance of the battery.
Does the amount of electric current flowing in a conductor depend in part on the pressure under which it flows?
Yes. Pressure being voltage. Voltage divided by resistance equals current.
How can you determine the resistance of a current?
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
Does resistance depend upon current?
The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.
What does a current in a circuit depend on?
current depends on applied voltage and resistance.
What does the size of the current depend on?
A: The EMF and total resistance
Relation between voltage and RPM?
voltage depend on current and resistance r.p.m depend on no of pole
Does the induced current depend on the resistance of the circuit?
In general, yes, it does. For example, if you move a conductor in a magnetic field, this will induce a certain voltage between the extremes of the conductor; the corresponding current will then depend on the resistance.
Why ammeter resistance is in parallel?
To by pass the extra current from the limit of Galvano meter & this parallel resistance value depend upon the by passed current.
What does the size of a current depend upon?

Is the resistance lower if you have a high current?
Lower than what? For the same voltage, a lower resistance means higher current. But beware, the voltage itself might depend on the current - thus - with a fixed resistance if you change the voltage, you will increase the current in the same proportion. Some things become higher resistance if they get hot (a tungsten filament in a lamp). Other things become lower resistance if they get hot (semiconductors). So it can all depend on what kind of circuit you have.
You are just asking that let us assume you have connected 2 or 3 resistors in a circuit and the current flowing through the circuit and from all the resistors will be same but how?
If the resistors are connected in series, the total resistance will be the sum of the resistances of each resistor, and the current flow will be the same thru all of them. if the resistors are connected in parallel, then the current thru each resistor would depend on the resistance of that resistor, the total resistance would be the inverse of the sum of the inverses of the resistance of each resistor. Total current would depend on the voltage and the total resistance
What is electronic resister?
Electronics resistor are a basic passive element it oppose the flow of current . the opposition depend upon the value of that resistance high value resistance will only able to flow some few amount of current through them. but low value of resistance allow to flow large current through them.
What does the amount of current flowing in each branch of a parallel circuit depend on?
It depends on the resistance (or impedance) of that branch alone.
Why does a motor have a bigger resistance than a bulb?
There is no particular reason why a motor should have a bigger resistance than a bulb. A motor's resistance must depend on what current it draws at the particular voltage it was designed to run on. Equally, a bulb's resistance must depend on what current it draws at the particular voltage it was designed to run on. A particular motor may have a higher resistance than one kind of bulb but that same motor may have a lower resistance than another kind of bulb.
