WebThe efficacy of the fluorescent tube will range from around 16 lumens per watt for a 4-watt tube with a regular ballast to more than 100 lumens per watt for a tube featuring a modern electronic ballast. The level of light emitted from the fluorescent tube is also affected by the lamp temperature in the coldest area of the lamp. WebAnswer (1 of 2): Ohm’s Law (50v / 10 ohms) tells us that the running resistance asks for 5 amps of current. This means that the 30 volt difference also asks for 5 amps, since this is a series connection. Again from Ohm’s Law: E = IR, and so 30 = (5) (R) Divide both sides by 5, and you get R = 6... rick eddy morris ilWeb2 Mark s.
