Date Have 4 a Maloney TAGE, CURRENT AND RESISTANCE Worksheet a) How my resistance = potential difference current R = V Units: R is measured in ohms () solve for the unknown measurement. V is measured in volts () I is measured in amperes (A) 1 = 10 A R = 1500 0 2 b ) 1 = ? R = 200 0 C) 1 = 15 A V = 240 V R =? V = 110 V SA OF 10 M 2. Find the unknown quantity (CONVERT to the base unit FIRST, then solve). a) 1=? R = 20 Q b ) R = ? C) 1 = 15 A V = 350 mV = 1 = 25 mA = A R = 7333 mQ = V = 110 V V = ? WORD PROBLEMS - Be sure to check your units before solving the following questions! 3. How much resistance does a light bulb create if it has a current of 25 mA around it in a 9 V circuit? 1 = 25 mA = V=. R = ? 4. How much current flows through a 16 V battery that has a resistance of 5.1
