Which of the following defines "battery" under the Penal Code?

Battery is defined under California Penal Code 242, which specifies that battery occurs when a person unlawfully uses force or violence against another person. This definition covers any intentional and unlawful physical contact that is harmful or offensive, regardless of whether it causes injury. The key element of battery is the actual application of force, even if the harm is minimal.

Understanding this definition is crucial for recognizing the legal implications of battery, as it holds individuals accountable for their actions even if the resulting injury is not severe. The other options refer to different legal terms: PC 197 pertains to justifiable homicide, PC 192 addresses manslaughter, and PC 245 relates to assault with a deadly weapon. Each of these codes pertains to distinct offenses, which is why they do not apply to the definition of battery.
