15 k ohms with a 10% tolerance.
1000 ohms = 1Kohm; silver is the tolerance band of the resistor. Silver signifies plus or minus 10%. The fourth band is always the tolerance band. If there is no tolerance band, the tolerance is plus or minus 20%. A gold band would signify plus or minus 5%.
brown, red, brown, silver = 120 ohms
The value of a resistor with color bands brown, black, black, silver, and brown is calculated as follows: The first two bands (brown and black) represent the digits 1 and 0, giving a base value of 10. The third band (black) indicates a multiplier of 1 (10^0). The fourth band (silver) signifies a tolerance of ±10%. Thus, the resistor has a nominal value of 10 ohms with a tolerance of ±10%.
When a resistor has a 4th color band, its color is either gold or silver, so I will assume the color bands are white-white-white-gold. The resistance is 99 GΩ ± 5%.
220 ohms with a 10 percent tolerance. Red is 2 and brown is 1. Brown is in the multiplier band so it is 10 times the value in the first two bands. Silver is in the tolerance band. Gold would have been a %5 tolerance device.
That would be a 200 Ohm resistor, and you didn't mention the tolerance, so I'm guessing you didn't see another band which means the tolerance would be at 20%
The tolerance of a resistor is basically a measure of how close the actual resistance of that particular resistor is to the stated resistance. For example, a "220 ohm" resistor with a tolerance of 10% (silver band) has an actual resistance somewhere between 198 and 242 ohms.
The color bands on the resistor indicate its resistance value: brown (1), black (0), and red (multiplier of 100). This means the resistance is 10 multiplied by 100, which equals 1000 ohms. Therefore, the correct answer is D. 1000.

Orange, orange, brown is 330 ohms.
The resistor with the color code red-red-brown-silver has a resistance of 22 ohms with a tolerance of ±10%. The minimum resistance is 19.8 ohms (22 - 10% of 22), and the maximum resistance is 24.2 ohms (22 + 10% of 22). Using Ohm's Law (I = V/R), the minimum current is approximately 0.76 A (15 V / 19.8 ohms) and the maximum current is about 0.62 A (15 V / 24.2 ohms).
