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.

No such resistor exists. Any resistor placed in parallel with a 6.0 ohm resistor is going to reduce the combined resistance below 6.0 ohms.
The combined resistance will be 2 Ohms.
E/R=I. 100/50=2 amps.
The current would be about 20 volts.

No, a 2.2k ohm resistor and a 220 ohm resistor are not the same resistance. The "k" in 2.2k ohm stands for "kilo," which represents a multiplier of 1000. Therefore, a 2.2k ohm resistor is equivalent to 2200 ohms, while a 220 ohm resistor is simply 220 ohms. The difference in resistance values is a factor of 10 due to the kilo prefix.
