Yes, a variable resistor is the same as a potentiometer, or pot in short is what it's also called. Trimmer is also often used. Most volume knobs or volume sliders are similarly also potentiometers. Hope this helps!
You should use the same size resistor; a 47 kilo-ohm.CommentThe correct spelling is 'kilohm'.
Yes, a 47 ohm resistor can be used in place of a 47E resistor, as "47E" typically denotes a 47 ohm resistor where "E" represents ohms in certain notations. However, ensure that both resistors have similar power ratings and tolerances for optimal performance in your circuit. Always double-check the specifications to ensure compatibility with your application.
On a standard four band resistor: yellow, violet, black, and gold.
The time-constant is the resistance times the capacitance, so that's 47 x 47 and because the capacitance is in microfarads, the answer is in microseconds.
is 4.7 and 47 the same
A tolerance of 5 percent for a 47-ohm resistor means that the actual resistance can vary by ±5 percent from the nominal value. This translates to a possible resistance range of 44.65 ohms to 49.35 ohms. In practical terms, a resistor with this tolerance may measure anywhere within that range while still being considered within specification. This allows for some variability in manufacturing while ensuring the resistor performs adequately in its intended application.
47/100 is the same as 0.47
47
50
47/5
It's still 47, since you are adding and subtracting the same amount.
It is a linear equation in one variable, x. And although you did not ask for it, the solution is x = 94/2 = 47
