Marie V. Brittan Brown invented the first home security system in the 1960s. Her invention included a series of peepholes, a camera, and a monitor that allowed homeowners to see who was at their door before answering. She also developed a remote control that could unlock the door and alert the police, laying the groundwork for modern home security technology. Brown's innovative design was patented in 1969.

If the voltage is 15 V and resistance is color coded red-red-brown-silve what are the maximum and minimum possible current.?
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).
Who was the first woman to invent?
Since a computer can only be invented once, you would be better off asking who was the first person to invent computers. In 1939, John V. Atanasoff and Clifford Berry developed the Atanasoff-Berry Computer (ABC) at Iowa State University, which was regarded as the first electronic digital computer. So, in short, it was a man, not a woman, which is understandable based on the attitude towards women in the workplace and in school in the early 20th century and earlier. It would be very hard for anybody, man or woman, to invent something when they were not allowed to attend college.
