Is current is drop when it flowing through the resistor?
Current flows in loops, voltage drops across elements. With relation to current, what flows in, must flow out, so no, current is not dropped across a resistor, it flows through a resistor and voltage is dropped across the resistor.
Does voltage flow across or through a resistor?
No. If a voltage is applied across a resistor, a current flows through it.
How much current flows through a resistor with zero potential difference?
No current flows when the the voltage is zero.
Does current flow through a resistor or across a resistor?
Normally through the resistor's internal construction. It flows through any part of the resistor that has low resistance- be it anywere. And then there's this. It might be that one should consider that current flows through a resistor and voltage is dropped across a resistor. Perhaps this is where the question began. The former is fairly straight forward. The latter can be vexing. Voltage is said to be dropped across a resistor when current is flowing through it. The voltage drop may be also considered as the voltage measureable across that resistor or the voltage "felt" by that resistor. It's as if that resistor was in a circuit by itself and hooked up to a battery of that equivalent voltage.
What voltage is developed across a 330 Ω resistor if 100 mA of current flows through it?
33V
If a current of 2 amps flows through a 12 ohm resistor what is the voltage across the resistor?
V = (I) x (R) = 2 x 12 = 24 volts
The total current that flows through a circuit is the same as the current that flows through each individual resistor connected in series?
True
How much current flows through a resistor of 285 ohms if the potential difference across the resistor is 122 volts?
Use Ohm's Law, i.e., V=IR here, V=voltage I=current R=resistance
What voltage is developed across a 6 Ω resistor if 3 A of current flows through it?
The answer is 6 ohms x 3 amps which is 18 v.
Why does a resistor heat up when an electric current flows through it?
Current moving through a resistor causes it to heat up because of the flowing electrons bumping into the atoms in the resistor.
What is capacitive effect in antenna?
The capacitive effect is an element's opposition to a change in AC voltage. The resistor will develop a positively charged current at it flows through a capacitor. This will prevent a change in the initial voltage.
What is the current that flows through an unloaded voltage divider?
The Bleeder current.
